Hello all.
I'm currently posting my first game in Google Play, and want to add login, scoreboard, achievements...
I've configured everything properly, added the scoreboard, created the OAuth, generated the signed keystore, properly added the required IDs, so on.
When I first opened the game using a signed debug apk it worked fine. I was able to login, logout, check my score, and the leaderboard was working fine.
After I closed and opened the game again, the login wasn't been automatically, and when I tried to login it just starts to open the login screen, but instantly closes it and returns to the game, and I'm unable to check the scoreboard.
The only non-native plugin I'm using is the Google Admob Plugin, for showing ads in the game.
Any advices on where to check or what to do?
If more information is required, please let me know.
Thanks in advance
